Notes: Overton et al. (2006a) clarified the complex nomenclature of this widespread selleck species. They also pointed out that Hypocrea lactea sensu Doi (1972) is probably a different taxon in Japan. Hypocrea citrina differs from other species forming effuse stromata by growth on soil and forest debris. It forms the largest stromata known in Hypocrea. H. sulphurea differs

e.g. by distinctly brighter stroma colour, occurrence on Exidia on branches, larger ascospores, lack of hairs on the stroma surface and lack of chlamydospores in culture. Hypocrea pulvinata differs from H. citrina by its occurrence on polypores, a tendency to form determinate pulvinate stromata, inhomogeneously distributed pigment and verrucose hairs on the stroma surface, lanceolate ostiolar cells, and slightly smaller, more or less monomorphic ascospores. H. auranteffusa, H. margaretensis, STA-9090 cell line H. luteffusa, and H. rodmanii differ e.g. by minute cortical cells and green-conidial anamorphs. The moniliform surface hyphae on PDA around the plug seem to be characteristic for H. citrina; in addition all fresh isolates of H. citrina formed a yellow to orange pigment on PDA, particularly at 30°C. This ability may be lost in older strains, as the

CBS strain studied by Overton et al. (2006a) did not form a distinct pigment. Hypocrea decipiens Jaklitsch, K. Põldmaa & Samuels, Mycologia 100: 981 (2008a).
